toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() =>
"ViewingConditions(n: $n, aw: $aw, nbb: $nbb, ncb: $ncb, c: $c, nc: $nc, "
"rgbD: $rgbD, fl: $fl, flRoot: $flRoot, z: $z)";
